Right, but as - I repeat - Copyright does not cover ideas and information themselves but only the form or manner in which they are expressed then the computers information isn't the point - the expression of that information is. Which is why it is not actually in violation to have a mp3 but only to upload or play it - as that is the expression. The digital data is not actually copyrighted. Which is, again, why white noise makes no sense to copyright - it's random noise.
